Plant Services - July 2008 - (Page 38) nfavorable market conditions have shut down many plants temporarily. Others have regularly scheduled shutdowns during the year. Maintenance departments frequently take advantage of these opportunities to repair or perform testing that can’t be done when hydraulic machinery is operating. But given the lull in the action, many times the only attention a hydraulic system gets is an oil and filter change. If those are the only two tasks on your work order, they won’t necessarily increase reliability. You’ll need to perform several other checks and procedures during down periods to boost the odds of gaining system efficiency and operation when production demands are high. The following preventive maintenance checks will reveal other maintenance work that will improve system and machine performance. U Maintenance mechanics and electricians chuckle when I tell them that the reservoir should be cleaned at least once a year. Clean the reservoir Now is an ideal time to clean the reservoir (Figure 1). Maintenance mechanics and electricians chuckle when I tell them that the reservoir should be cleaned at least once a year. While consulting with a large wood products plant, the mechanic said that the reservoir on one system hadn’t been cleaned since the mill started up 17 years before. Beyond oil storage, the two main purposes of the reservoir are to allow contaminants to settle and to dissipate heat. If the reservoir isn’t cleaned, it’ll act as a heat sink and can cause the system temperature to rise above 140°F, the point at which oil starts breaking down, adding sludge and varnish to the system.
